White Screen - App content failed to load after launch released iOS app

I was upload my new flutter app to AppStore and it's got rejected due to this problem...
"the app content failed to load after we launch. "

But it's working fine when I test it on Simulator and as well as connected real device. But problem has been arising when I export the ipa for internal testing. After installed the exported ipa, when I launch it nothing is loading, just white screen.

I am using Xcode 10.1 and my selected method of distributiontion is 'Development'

Then I decide to debug the project and for this I just created new flutter project (with default code, floating button and counter functionality). And export ipa by using same Bundle Id and certificate/provisioning and same method. It was working fine!

Then I added the dependencies in .yaml file for this project, and export again without added any other code. Then the same problem is came to new project also.

I am using for libraries:

image_picker: ^0.4.10. ----------- (white screen problem)
path_provider: ^0.4.1 -------------(white screen problem)
flutter_colorpicker: ^0.1.0 --------- (working fine)
after_layout: ^1.0.7 ---------------- (working fine)

And the problem is with two libraries only, image_picker and path_provider. And flutter_colorpicker and after_layout working fine.

But don't know why all four libraries working fine when I test on connected iOS device and Simulator. problem is only arise when I export the ipa.

Please help me.

same problem here when test exported ipa..

@ZeroCool00

@ZeroCool00 My problem is solved. now let me solve yours

Did you run flutter build ios --release command before exporting ipa from Xcode?

if not then run this command in terminal and make sure you are in the project directory. I spend lots of time to find this problem, and this is happened because I miss that step when reading iOS release documentation.

You can read documentation on flutter.io, this step is under "Create a build archive"
https://flutter.io/docs/deployment/ios

If you problem not fixed then let me know, or if you are now facing problem in release command then update your flutter.

@geniecoder

@geniecoder brilliant brother.. it worked. Thank you so much

Probably related to #24641

Probably relate with #25167 too.

You are awesome!

thx,fix it

@geniecoder

@geniecoder this would be the same thing if you're deploying it via fastlane, right ?

  lane :beta do
    alphaBuild
    build_app(workspace: "Runner.xcworkspace", scheme: "Runner", configuration: 'Release')
    upload_to_testflight(skip_waiting_for_build_processing: true)
  end

  desc "Increment the build number based on the number of commits"
  lane :alphaBuild do
    # Return the number of commits in current git branch
    build_number = number_of_commits()
    Dir.chdir "../.." do
      sh("flutter", "packages", "get")
      sh("flutter", "clean")
      sh("flutter", "build", "ios","--build-number=#{build_number}","--release" ,"lib/main_staging.dart")
    end
  end

I'm running the beta lane which does the build ios --release before deploying the app. Sometimes I still get blank screens :/

try the next line

flutter clean
flutter build ios
flutter install

same problem this is terrible :/

It work when I do:

flutter clean
flutter build ios --release

And after Archive in Xcode and it works. But if instead of using xcode I want to use fastlane my app get refused because it's empty.
Here is my lane:

lane :beta do
    sh "cd ../.. && flutter clean && flutter build ios --release --target=lib/main-prod.dart"
    get_certificates
    get_provisioning_profile
    build_app(scheme: "Runner",
                  export_method: "app-store",
                  workspace: "Runner.xcworkspace"
                 )

    upload_to_testflight {
        skip_waiting_for_build_processing
    }

  end

It was working for a while but I guess since the last stable it's not for some reason

@jaumard

@jaumard I'm having the same problem when using Fastlane. Do you get it working?

@franzejr

@franzejr unfortunately no :/ I just do manual release for now. Didn't have time to check what's wrong with fastlane build...

Yeah. I did a manual build and it works fine. I'm trying to figure out. If I have some idea, I post it here.

GoogleService-Info inside the runner / runner folder inserted through x-code, I followed all the recommended steps, even though the application when sent to production gets the white screen when starting.

Flutter clean
flutter build ios --release

Xcode
Product -> Clean
Archive
Upload App Store

Any idea what that might be?

Same problem here. Any solution found? This is very annoying!!

I'm getting the same problem ^

doing pod update worked for me

@consuelogranata

@consuelogranata follow the steps as written

DO THIS BELOW

Xcode (Good to do)
Product -> Clean

IDE/Command-line (Must do to fix)
Flutter clean
flutter build ios --release

Xcode (Have to do anyways)
Archive
Upload App Store

DO NOT DO THIS BELOW

Flutter clean (Cleans the build directory - where ipa file is)
flutter build ios --release (Builds the release ipa file and creates build directory)

Xcode
Product -> Clean (Cleans the build directory - deletes the ipa file) <--- ISSUE
Archive (Uses the build directory - but from above, ipa is deleted)
Upload App Store (Uploads empty build) :(

I believe regenerating the Podfile as instructed with the new warning in #42029 (v1.10.15, so currently dev and beta channels) mitigates the ongoing issue where the wrong version of the Flutter.framework is embedded in the app.

I'm going to close this as fixed with #42029. That fix is on master, dev, and beta channels, but not yet on stable.

If you are on master, dev, or beta, follow the instructions you get in the warning by regenerating your Podfile via rm ios/Podfile then flutter build ios again. You can switch back to stable once you get the updated Podfile.

Closing. Please comment if anyone hits this issue after regenerating your Podfile on the master, dev, or beta channels.
